git config --list
touch .gitignore       # create .gitignore if it does not already exist

# To start a repo
cd ~/git
git init  # start new repo at this dir, creates .git/
git clone # get and start with existing repo
git clone git@git.astron.nl:desp/args.git
git clone git@git.astron.nl:desp/sampy.git

git status # what is in stage area and what is modified
git status -uno  # skip unversioned files

Three areas:
* working tree # local directory tree
| git add
v
* staging area (index)
|
v git commit
* history # .git repository with entire commit graph

# To use a repo
git add <dir>/<file>       # add to stage area, set for commit. Cannot add empty dir, need empty file in it
git add .                  # add all new and modified to stageing area
git diff                   # diff between file in working tree and staging area
git diff --staged          # diff between file in staging area and history

git config --local http://user.email "erkooi@gmail.com"
git remote # origin
git remote -v # full url

# To align with remote repo
# update from remote
git status # shows also origin/master, but not live
git fetch origin
git status # shows also origin/master, now with latest remote
git merge origin/master
git pull # get latest from remote repo, combines fetch and merge

# upload to remote
git push
git push origin master  # put local repo to remote repo

# On Github fork is a copy of the a repo in Github to get a repo on your account
git clone <url of fork> # get copy of fork repo, will be origin
git remote add upstream <url of original repo on Github> # will be upstream
git fetch upstream
git status
# commit local change on branch
# git push origin <branch name> # push to my fork repo on Github
# pull request on Github
# delete branch and fetch npstream if the pull request was accepted
git remote remove <remote name> # remove a remote repo


*******************************************************************************
* GIT workflow and review process using Gitlab
*******************************************************************************

https://ohshitgit.com/

We identify two persons in this process:
- the coder
- the reviewer

* Jira ticket defines the work to be done, e.g. L2SDP-26
* Coder works on branch with Jira ticket number as branch name

    git checkout master     # start on up to date master branch
    git pull
    git branch L2SDP-26     # creat branch using Jira ticket number
    git branch              # show branches
    git checkout L2SDP-26   # change working tree and stage area to branch

* Work on branch using git add, commit and push
* Manually run regression test to test the changes (for Casacore SW the merge
  request makes github automatically issue a regression test in the cloud, for
  FW we need to run the relevant testbenches manually. It is not necessary to
  rerun the entire FW regression test, it is sufficient to only run the
  regression test for the HDL libraries that were modified and the HDL
  libraries that could be impacted by the modification)
* Push the branch to the central repository at gitlab

    git push -u origin L2SDP-26   # first time to declare the branch at the remote


* Coder does merge request to reviewer using the central Gitlab GUI
* gitlab will warn if the branch will lead to a merge conflict, the coder then
  first has to fix the merge conflict by merging the master to the branch:
  The merge can use merging or rebasing, Ger typically uses merging. On local
  machine the coder resolves the merge conflict:

    git checkout master
    git pull
    git checkout L2SDP-26
    git merge master
    git status   # to see merge conflicts, edit file to solve merge conflict
    git add file
    git commit
    git push

* In gitlab do merge request to reviewer
* Reviewer reviews the code per line or in general comments in gitlab GUI,
  so reviewer does not need to pull the branch locally and also does not need
  to rerun the regression test.
* Use 'Open in Web IDE' button in gitlab GUI to see max about 10 changes,
  use 'Changes' menu on same page to see all changes. Green is new file,
  orange is change file, + is new lines - is removed lines.
* Coder does updates on branch until both coder and reviewer are ok, they are
  notified by gitlab
* When review is done then the reviewer does the merge.
* The merge automatically deletes the branch (if selected to do so in gitlab)
  locally the coder manually needs to delete the branch:

    git branch
    git checkout master
    git status
    git branch -d L2SDP-26
    git status

* Use Jira tag in commit message to have link between GIT and Jira. The link
  was made via Settings/Intergations/Jira

Note:
* In github a merge request is called a pull request
* Default a pull pulls the master. Typically it is not necessary to pull a
  branch because the reviewer does not need to compile and run the code and
  because typically only one coder works on a branch.

We hebben nog geen regel over sub-branches wel of niet. Als er geen duidelijk voordeel is dan zou
ik alleen vanaf de master branchen, omdat je de branches dan onafhankelijk houdt van elkaar en
alle branches dan dezelfde referentie hebben. Voordat je een merge request van je branch naar een
bovenliggende branch doet, moet je eerst die bovenliggende branch mergen naar je branch.

*******************************************************************************
- space tools menu links onder om secties the ordenen.
- space tools menu, content tools, custom export to PDF --> to export multiple
  pages to PDF and to preserve th ASTRON logo in the export

I notice that in a Confluence document from Gijs that if I try to do a comment
on a text that contains capital charcters it fails, and if I try to place the
comment on text with only small characters it accepts the comment. Strange,
but for me it is an ok workaround.


Sometimes in a Confluence document in edit mode all Figures have collapsed into
small narrow icons. I can recover them by selecting the Figure icon and then
choosing the expand button  in the bar on top or below the Figure. Weird, but
for me it is an ok workaround,

You won't be asked for a (bastion) password. The certificate you've just generated will last for twelve hours. Once it's elapsed, the only step from the above you need to perform again is

$ step ssh login kooistra@astron.nl --provisioner "keycloak"

alias mystep='step ssh login kooistra@astron.nl --provisioner "keycloak"'

Whereupon you'll be good for another twelve hours. The above command is a great candidate for a shell alias.

* Screen to run a terminal session without ssh connection
*******************************************************************************

https://linuxize.com/post/how-to-use-linux-screen/

screen --version

Basic Linux Screen Usage

On the command prompt, type screen.
Run the desired program.
Use the key sequence Ctrl-a + Ctrl-d to detach from the screen session.
Reattach to the screen session by typing screen -r.


To start a screen session, simply type screen in your console:

screen
screen -S session_name

This will open a screen session, create a new window, and start a shell in
that window. Now that you have opened a screen session, you can get a list of
commands by typing:

Ctrl+a ?

When you start a new screen session, it creates a single window with a shell
in it. You can have multiple windows inside a Screen session.
To create a new window with shell type Ctrl+a c, the first available number
from the range 0...9 will be assigned to it. Below are some most common
commands for managing Linux Screen Windows:

Ctrl+a c Create a new window (with shell)
Ctrl+a " List all window
Ctrl+a 0 Switch to window 0 (by number )
Ctrl+a A Rename the current window
Ctrl+a S Split current region horizontally into two regions
Ctrl+a | Split current region vertically into two regions
Ctrl+a tab Switch the input focus to the next region
Ctrl+a Ctrl+a Toggle between the current and previous region
Ctrl+a Q Close all regions but the current one
Ctrl+a X Close the current region

You can detach from the screen session at any time by typing:

Ctrl+a d

The program running in the screen session will continue to run after you detach
from the session. To resume your screen session use the following command:

screen -r

In case you have multiple screen sessions running on your machine, you will
need to append the screen session ID after the r switch.
To find the session ID list the current running screen sessions with:

screen -ls

There are screens on:
    10835.pts-0.linuxize-desktop   (Detached)
    10366.pts-0.linuxize-desktop   (Detached)
2 Sockets in /run/screens/S-linuxize.

If you want to restore screen 10835.pts-0, then type the following command:

screen -r 10835

When screen is started, it reads its configuration parameters from
/etc/screenrc and ~/.screenrc if the file is present. We can modify the default
Screen settings according to our preferences using the .screenrc file.
Here is a sample ~/.screenrc configuration with customized status line and few
 additional options:

~/.screenrc
# Turn off the welcome message
startup_message off

# Disable visual bell
vbell off

# Set scrollback buffer to 10000
defscrollback 10000

# Customize the status line
hardstatus alwayslastline
hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{= kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B} %m-%d %{W}%c %{g}]'
Copy

* uex in screen lijkt eerst niet op te starten,
  matlab wel dus het ligt niet aan GUI, daarna lukts uex wel.
* :kooistra@dop386:~/git/hdl>  --> in gewone terminal
* ::kooistra@dop386:~/git/hdl> --> in screen terminal

*******************************************************************************
* Quartus Qsys IP files in GIT
*******************************************************************************

1) Designs without QSYS: unb2b_arp_ping
Met meld blijkt dat de ip dir van unb2b_arp_ping en unb2b_minimal gelijk zijn
in de STAT-266 branch. Dat komt omdat je ze gecopieerd hebt en omdat
unb2b_arp_ping geen QSYS heeft zijn ze dus ongewijzigd.

Aangezien unb2b_arp_ping geen QSYS heeft, en ook niet zou krijgen, is het
beter om de unb2b_arp_ping/quartus/ip dir van unb2_arp_ping te deleten.

2) Designs with QSYS
Elk design op basis van unb2_minimal heeft zijn eigen QSYS ip files:

> ls $RADIOHDL_WORK/boards/uniboard2b/designs/unb2b_minimal/quartus/ip/qsys_unb2b_minimal

Als een design meer MM ports heeft dan heeft het ook meer ip files, bijv.
qsys_unb2b_heater_reg_heater.ip voor de unb2b_heater.

Het is kennelijk voor QSYS nodig om naast de .qsys file ook de ip/ files in de
repository te bewaren. Het is dus ook nodig om ze per design te bewaren, want
elk design heeft zijn eigen naam en extra MM slaves tov unb2b_minimal.

Echter het blijkt dat een nieuw design ook dezelfde ip/ files als unb2_minimal
mag gebruiken, dus zonder naamswijziging.

* Quartus version
*******************************************************************************

Quartus version meeting minutes 13 may 2020 (RW, LH JH, EK):

1) UniBoard2b IP is created using Quartus 18.0, same as used for ARTS SC3.

2) UniBoard2b synthesis is done with Q18.0 or newer. In case of a newer Quartus version we rely on Quartus to upgrade the Q18.0 IP for synthesis which works fine sofar. We also rely on that the Q18.0 models are still sufficiently correct.

2a) Jonathan uses Q19.4, because Q18.0 does not work remotely via ssh.
2b) Reinier uses Q19.2, because that is the latest version that support OpenCL without microprocesor.

3) UniBoard2c IP was created using Q19.4 by Jonathan, but we need to reconsider going to the latest Quartus version and recreate the IP, when we continue with the pinning and test designs for UniBoard2c
